The sky’s the limit, or is it? Find out if your young audience can spy familiar favorites, whether Debussy’s moon or Williams’ stars, or, of course, Holst’s planets, stylishly trimmed down to a universally-appealing orchestration. Through the lens of a pink panther or a savvy secret service agent, your young detectives can gather intelligence on Stephenson’s own specialized gadgets for these subjects: a “Celestial Suite” based on astronomers through the years, or a “Trench Coat” for the young spies among us.
